3 Claims. 1

The present invention relates to safety appliances of the type requiredby workmen in building construction and operations in which scaffoldingor the like is commonly used for the support of the workmen when workingat more or less high levels above the level of the ground.

The principal object of the invention, therefore, is to provide a tie oranchoring device which may be employed by the workman for safetypurposes, and which is adapted to be readily and conveniently secured oranchored to one of the vertical supporting ropes or cables of suchscaffolding as is used in construction or building operationsand thelike.

For this purpose we provide an attachment of simple construction whichis adapted to be readily attached in secure holding relation to one ofthe vertical ropes or cables of the scaffold, and also provided with aflexible connection with suitable harness or holding means worn by theworkman making use of the appliance.

It is also sought to provide an appliance of the character indicatedwhich may be conveniently adjustable with reference to its connectionwith the supporting rope or cable of the scaffold and also readilydetachable therefrom when not in use.

With the foregoing general objects in view the invention will now bedescribed by reference to the accompanying drawing illustrating anappliance constructed in accordance with the purposes thereof and whichhas been found suitable for the embodiment of the proposed improvements,after which those features and combinations deemed to be novel andpatentable will be particularly set forth and claimed.

In the drawing:

Figure 1 is a perspective view illustrating a safety appliance embodyingthe present invention and shown in operative position as applied to oneof the supporting ropes or cables of a scaffold; and

Figure 2 is a similar view on a larger scale, showing said device andthat portion of the supporting cable to which it is applied.

Referring now to the accompanying drawing in detail, this shows theimproved appliance as applied to one of the supporting ropes or cables 5of what may be referred to as a conventional form of scaffoldconstruction (the other parts of which are not illustrated). To thiscable 5 the appliance is designed to be secured or anchored by formationof a loop in the cable which is adapted to be held by a binding orfrictional engagement with the device.

For this purpose the appliance comprises a metal rod or link 'I which isprovided at one end with an eye or loop 8 for connection with a swivelI0 at one end of a suitable strap I2, which is provided at its other endwith a link I4 for connection with a ring I5 or the like forming part ofthe conventional shoulder harness I6 lworn by the workman, asillustrated in Figure 1.

Adjacent to each of its ends, the link or rod 'l has rigidly securedthereto a rigid hook element I8 designed for loose hooking anddetachable engagement with the adjacent portions of the cable 5, wherebythe rod or link 1 may be maintained in approximately parallel relationto the cable, as illustrated.

Between its end, said link or rod 1 is bent upon itself to form an openhook portion 2Q, preferably pointing in a downward direction, or awayfrom the adjacent end of the rod; and adjacent to said hook portion 20the end of saidlink or rod is formed with a terminal hook 22, preferablyturned in a direction for cooperating with the hook 2U for supportingand anchoring a looped portion of the rope or cable 5, as illustrated inthe drawing.

The appliance is placed in its operative position as illustrated, bysimply attaching both of the open hooks I8 in sliding engagement withthe cable 5, and then doubling a portion of the cable between said hooksI8 to form a small loop 25 which is then swung around underneath thehook 20- and finally hooked over the top or end h'ook element 22, asshown.

By J@his means the improved appliance is rmly gripped and held againstany ,downward movement on the cable 5 and therefore serves as a safe andsecure anchoring means for the workmans strap connection I2 which isconnected with the lower eye or loop 8 of the appliance.

Moreover the safety appliance is not only readily -and quickly appliedinto operative position, but may also be easily and convenientlyadjusted from time to time as required to accommodate any changes in theworking position of the user of the appliance.

It will therefore be apparent that a simple, inexpensive and at the sametime highly eilicient .device has been devised for fulfilling thedesired objects of our invention; and while we have illustrated anddescribed what is now regarded as the preferred and most practical formof construction for embodying the features of improvement, it is desiredto reserve the right to make any changes or modifications which mayfairly fall Within the scope of the invention as dened by the appendedclaims.

What We claim is:

1. A safety appliance for attachment to scaffolding ropes or cables,comprising a rod or link provided with' a holding connection for theuser of the appliance and also having means at its opposite endsfronloose detachable .engag ement With saidrope Vor cable, andintermediate hoolgV elements for detachable hooking'engagement with a,looped portion of said rope or cable of the scaffolding.

'supporting ropes or cables of scaffolding or the Y g like, comprising arod having a holding connection for theuser of the appliance andalsomeans for hookingdetachably in engagement with spaced points on saidrope or cable, the intermediate .portion of said rod being bent uponitself to form an open hook for engagement with a looped 2. A safetyappliance for attachment@to:,.the.,, A,

supporting ropes or cables of sca'olding on the like, comprising a rodor link provided-'ai holding connection for the user of the appliance'and ralso with terminal hookingmeans. fordetach-- able engagement Withsaid rope or cableth'e, intermediate portion of said rod or link havingportionzof said rope or cable, said rod terminating adjacent ,to saidopen h'ook in an oppositelyk turnedY hook for holding engagement withsaid looped'v4 portion of the supporting rope or cable.
